nest, but should be put beneath the straw, so that the eggs will not 

 rest upon it. Xaphthaline is not poisonous, however, and may be 

 handled without danger. 



OTHER LICE OX POULTRY. 



Chickens are subject to the attacks of various other lice with 



habits similar to those of the species mentioned, but most of them 



are not common. One, Menojyon hiseriatum 



Piaget, is very like the common " hen louse," 



but larger, and with a more elongate body. 



Others belong to the genera Lipeurus (fig. 4), 



Goniodes (fig. 5), and Goniocotes (fig. 6). 



Several of these are known as " gray sucker 



lice." They do not move around as much 



as the Menopons and are often confined to 



one part of the boch-. 

 Sometimes they biiry 

 their heads in the scales 

 of the skin or close to 

 the base of a feather 

 and remain a long time 



in one position. The species of Lipeurus 

 are more slender than the common lice, 

 and the Goniodes and Goniocotes are 

 broader, with more prominent feelers or 

 antennae, and with darker spots on the bor- 

 ders of the body. 

 The remedies used 

 against the com- 

 mon hen louse will 

 at the same time 



destroy any of these other lice that ha])- 



j)en to be present.

 LICE.

Since lice and mites have no Avings 

 and can crawl but short distances, it is 

 evident that they are disseminated only 

 from fowl to fowl. But if an infested hen 

 or rooster is brought to the flock the parasites soon spread to all the 

 birds. There is a possibility that lice may be carried by certain bird 

 flies, but such flies have been found so rarely on poultry that this
